About H93

H93 is the ICD-10-CM diagnosis code for other disorders of ear, not elsewhere classified. It belongs to block H90-H94 (other disorders of ear) and chapter 8 (diseases of the ear and mastoid process). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H93.0 (ear), H93.1 (tinnitus), H93.2 (perceptions), H93.3 (nerve), H93.8 (ear), H93.9 (ear) and H93.A (tinnitus).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
